Question

Find the surface area and volume.

Answer 1

Answer:S = 12(3 + 6)π ft² = 12(9π) ft² = 108π ft²V = 36(3π) ft³ = 108π ft³:

Answer 2

S = 2π(6x) + 2π(6²)

= (12x + 72)π ft²

= 12(x + 6)π ft²

V = π(6²)(x) = 36xπ ft³

12(x + 6) = 36x

12x + 72 = 36x

24x = 72

x = 3

S = 12(3 + 6)π ft² = 12(9π) ft² = 108π ft²

V = 36(3π) ft³ = 108π ft³
